+  before release.

+  * `main` is protected.

+* Verify the release on the GitHub Releases page.
+* If everything goes well, the authorized releases will receive an email
+  to review the pending deployment. If you are an authorized releaser,
+  you will need to approve the release deployment run. If you are not,
+  you will have to wait for an authorized releaser to do so.
+* Double check it looks okay at https://rubygems.org/gems/minfraud and
+  https://www.rubydoc.info/gems/minfraud.
+* Make a PR and get it merged.
